Abstract (en)
[origin: WO8804197A1] In order to obtain a particularly effective and long-living catalyst carrier body useful for decomposing by catalysis individual parts of gaseous or aerosol mixtures in gas streams, in particular for decomposing by catalysis the hydrogen peroxide contained in the air, the catalyst carrier body has a supporting body of carbon particles mutually linked without any binders. The carbon particles comprise a first coal fraction forming the supporting structure having a particle size of between 500 and 5000 $g(m)m an intermediate pore width of the supporting structure between 50 and 1000 $g(m)m and an inner surface of the particles of between 0 and 100m?2/cm?3, and a second coal fraction of highly-porous activated carbon with an inner surface of between 600 and 3500m?2/cm?3 and a particle size of between 0.1 and 500 $g(m)m. The activated carbon particles are deposited in the intervals between the particles of the first coal fraction, and an inorganic catalytic substance, in particular noble metals and their compounds, is applied on the supporting body and/or on the activated carbon particles.
